Extension:Math/MathJax testing

When you click a MathJax formula, you get an instantly zoomed version of it for improved readability. MathJax formulas can also copied and pasted, and scaled without loss of quality for printing, higher resolution displays, or better readability.

MathJax is a JavaScript display engine for mathematics. It's an alternative to PNG rendering for Wikimedia sites. MathJax is slower to render, but more scalable (infinite zoom) and manipulable than PNG.

MathJax is currently enabled on this wiki (mediawiki.org), but you have to explicitly enable it in your user preferences (under Appearance -> Math). Otherwise you'll still see the old-school PNG images.
